Telstra Caller ID Restrictions from November 2021

If you currently have your ServiceM8 Phone outbound Caller ID set to a Telstra phone number, whether landline or mobile, you will be impacted. However, we have taken steps to minimise disruption to your business. 

To maintain your service continuity, choose from one of two simple options:

1. Port your Telstra number to ServiceM8 Phone. Choose this option if you want to continue using your existing phone number (mobile or landline) as your outbound Caller ID. This process takes a few weeks, so you should act immediately. Jump to this section for more information.

-OR-

2. Use your ServiceM8 Phone number as your Caller ID. If you currently have a Telstra number set as your outbound Caller ID, you'll need to set it back to your ServiceM8 Phone number, so calls you make to Telstra numbers don't get blocked. Jump to this section for more information.

If you would like to continue using your existing Telstra phone number as your outbound Caller ID with ServiceM8 Phone, you must "port" your number and service to ServiceM8 Phone. 

Some key points:

• There is no charge to port your phone number to ServiceM8 Phone. 
• Both landline and mobile numbers can be ported to ServiceM8 Phone in Australia.
• You must maintain your Telstra service/account up until the porting process is complete, after which you can cancel your account with Telstra.
• The porting process takes 4-6 weeks, so the sooner you start, the better.
• Minimum usage requirements of ServiceM8 Phone (3 months & 1000 calls) still apply before you can port your Telstra number to ServiceM8 Phone.

The Australian Communications Alliance and the Australian Communications and Media Authority have introduced the Reducing Scam Calls (C661:2020) industry code to identify, track, block, and disrupt scam calls. The full code can be found here.

From November 2021, one of Telstra's responses to the code is to block calls where the Caller ID is set to a Telstra number, but the call was not made from a Telstra service. This is designed to combat scammers, including the practice of “number spoofing” e.g. where overseas scammers set their caller ID to a different/local number to trick potential victims into answering their calls.

Setting your outbound Caller ID to your existing Telstra number with ServiceM8 Phone has always involved a security verification process, to ensure only you as the true owner of the phone number can use it as your Caller ID with ServiceM8 Phone. However, this will not prevent your calls being blocked under Telstra's new measures — please refer to Options 1 & 2 above.
